“…It is located on the Antarctic Peninsula and contains many research stations (Polyakov et al, 2020). There are several reports about atmospheric aerosols conducted in the Antarctic Peninsula (Artaxo et al, 1992;Ángeles et al, 2020;Hong et al, 2020;Polyakov et al, 2020;Fan et al, 2021;Szumińska et al, 2021;Gonçalves et al, 2022). However, despite progress in characterizing and determining the origin of atmospheric aerosols (Marina-Montes et al, 2020), there is still limited information on the source areas of air masses that move particles toward the white continent.…”

Antarctica is a remote and relatively pristine region, but the regional transport of aerosols may be a source of pollution, especially in the Antarctic Peninsula. Few studies have characterized atmospheric aerosols and evaluated the contribution of their emission sources. The Peruvian Antarctic research station Machu Pichu (ECAMP, by its Spanish acronym) is located on King George Island in the Antarctic Peninsula. During February 2020, atmospheric particulate mass (PM10 and PM2.5) was sampled and analyzed to characterize its elemental composition and was supplemented by measurements of equivalent black carbon and aerosol size distributions. Chemical elements were analyzed by inductively coupled plasma mass spectrometry (ICP-MS), multivariate techniques, and enrichment factors. The most abundant elements in PM10 and PM2.5 were Na, Fe, Mg, and Si, with the most important local sources being marine (Na, Mg, Mn, Ca) and crustal (Fe, Al, P). Sources of weathering (Ba and Si) from glacial thawing and sources of combustion linked to the use of oil (V) and emission of black carbon were recorded. Air mass back-trajectory analysis using the HYSPLIT model helped identify external sources of particulate matter in the air masses reaching the ECAMP site. Overall, this study supports the growing evidence of the anthropogenic impact of distant and local sources on the white continent.

“…Among these commercial BC monitors, lter-based absorption photometers, such as aethalometers, are the most widely used in air quality monitoring stations of their robust precision design (Kalbermatter et (Sharma et al, 2022) or diurnal (Yan et al, 2022), have been observed. In the same way, there were analyzed differences in BC concentrations in rural and urban environments (Kouassi, 2021) or their effects in remote places such as Antarctica (Gonçalves Jr. et al, 2022).…”

This work evaluates Black Carbon emissions produced in Ciudad Valles, San Luis Potosí, México, during the harvest 2020–2021 of Ingenio Plan de Ayala and its association with the sugarcane sector in its area of influence. Black Carbon concentrations were measured each hour by the 7-wavelength aethalometer (AE-33) from November 13, 2020, to June 7, 2021, at Tecnológico Nacional de México - Campus Ciudad Valles, located northeast of the city, approximately 1 kilometer from Ingenio and bordered by the sugarcane area. The maximum daily concentration recorded was 4.5 ± 0.072 µg m− 3 with a daily average of 0.9 ± 0.014 µg m− 3, enough to increase the mortality of the long-term exposed population by almost 6.0% moreover, according to the World Health Organization, and to cause environmental and productive effects. The burning of fossil fuels represented 62.9% of the total Black Carbon, indicating that contrary to official statistics, Ingenio Plan de Ayala may continue using fuel oil. Likewise, there was a statistically significant difference in Black Carbon concentrations during harvest and no harvest periods, indicating a direct relationship between its emissions and the sugarcane sector of this region. The highest concentrations were in the surrounding area of Ingenio Plan de Ayala and sugarcane lands, which supports the previous theory. With the results obtained, the bottom line is that evaluating other agricultural burning emissions near the growing cities is necessary to minimize adverse effects on human health and reduce CO2eq emissions.
